FC6 kernel BUG when going to sleep

Hi All,
i'm running Fedora core 6 on a power book G4. I'm running the latest kernel.
I noticed problems after going to sleep/wakeup ( i've had applications 
stuck waiting on futexes , weird behaviours that disappeard after a 
reboot, implying badly messed up kernel structures ). I've got the 
following logs in /var/log/messages yesterday after going to sleep for 
the first time after upgrading to the latest kernel ( Linux kaluha 
2.6.18-1.2849.fc6 #1 Fri Nov 10 12:40:25 EST 2006 ppc ppc ppc GNU/Linux )
 From the logs i understand that the following is happening:
i'm closing the lid; pmud tries to put the system to sleep then comes 
the BUG, It somehow causes a waekup of the video card , network card , 
hard drive etc ... but then another crash :( then nothing ( sleep with 
all devices enabled ? ), until the wakeup this morning ....
This sounds pretty messed up . Is anyone else experimenting these problems ?
